Conclusions 1. It was established that diffusion coatings can be produced on boron carbide by gaseous-phase chemicothermal treatment in chromium and titanium halides, and a study was made of the effects of some parameters upon the depth and phase composition of the resultant diffusion layers. 2. Use of ammonium chloride as an activator of the process leads to the deposition of chromium and titanium nitrides. 3. The diffusion coating produced by chromizing contains chromium borides, carbides, and nitrides, while the coating produced by titanizing consists of a solid solution based on the cubic TiN structure with a parametera=4.28 Å. Coatings of such phase compositions are capable of reducing the reaction of boron carbide with metallic binders.
